Late surrender is a blackjack option that allows you to give up your hand and lose half of your bet only after the dealer checks for blackjack. This means that if the dealer has a natural blackjack (an ace and a 10 or face card), you cannot surrender and you lose your full bet. However, if the dealer does not have a blackjack, you can surrender and save half of your bet. This option can reduce the house edge by about 0.1 percent, depending on the number of decks and other rules.
Late surrender is more common than early surrender, which allows you to surrender before the dealer checks for blackjack. Early surrender is very advantageous for the player, as it can cut the house edge by 0.6 percent, but it is rarely offered by casinos. Late surrender is still a useful option, especially when you have a bad hand against a strong dealer card. For example, if you have a hard 16 and the dealer has a 9, 10, or ace, you have a very low chance of winning, so it is better to surrender and lose half of your bet than to risk losing it all.
To use late surrender, you must indicate your intention to the dealer before playing your hand. You can do this by saying “surrender” or by making a gesture of sliding your index finger across the table behind your bet. The dealer will then take your cards and half of your bet, and you are out of the round. You can only surrender after the first two cards are dealt, and you cannot surrender after splitting, doubling down, or taking a hit.
Late surrender is not always available, and some casinos may not advertise it even if they offer it. Therefore, it is important to check the rules of the game before you play and ask the dealer or the pit boss if you are not sure. You should also learn the basic strategy of when to surrender and when to play, as surrendering too often or too rarely can cost you money in the long run. A simple rule of thumb is to surrender hard 15 against a dealer’s 10, and hard 16 against a dealer’s 9, 10, or ace. Some variations of the basic strategy may also recommend surrendering hard 17 against an ace, or a pair of 8s against an ace, depending on the number of decks and the dealer’s hitting or standing on soft 17.
